In a field study Samiullah Khan investigated - under supervision of Martin Kainz and Thomas Hein - how particulate organic matter (POM) and dissolved organic matter (DOM) quantity and its biochemical quality changed between lake inflow and outflow as well as within the oligotrophic Lake Lunz from 2013 to 2015. In April he successfully finished his thesis with the title „Biochemical characterization of particulate and dissolved organic matter in pre-alpine Lake Lunz“.
